OC 12Cu2 configuring OCM yields crontab error

Hello,I've installed OPSCenter and now after following the instructions at:

http://docs.oracle.com/cd/E27363_01/doc.121/e25143/infrastructure.htm#OPCAG107

Configuring Oracle Configuration Manager

Now I am getting cron notifications from the oracleoc user:

Your "cron" job on hostname

/var/opt/sun/xvm/ocm/ccr/bin/emCCR -cron -silent start

 produced the following output:

 JAVA_HOME does not contain java.

JAVA_HOME is not a valid JDK/JRE directory.

Redefine JAVA_HOME to refer to a JDK/JRE 1.2.2 or greater and invoke

How should this be resolved? Thanks,

jeff
